The following fixes are in this patch:

Release of DirectX 12 support in Deus Ex: Mankind Divided:

As of today, users are also able to utilize the awaited DirectX 12 Graphics API. To activate this you are required to do the following:

Within your Steam Library, right-click on Deus Ex: Mankind Divided.

Select ‘properties’ from the context menu and navigate to the Beta tab.

From the dropdown menu, select dx12_preview then close the window.

After the game has downloaded the DirectX 12 supported build you can then toggle DirectX 12 from either the launcher window or from the Display options within the game.
Note that DirectX 12 requires a restart of the game if (de-)activated from within a running Deus Ex: Mankind Divided game session.

o WARNING: Using the DirectX 12 API can offer better performance on some systems, however, it will not be beneficial on all.
o Multi-GPU is not yet supported in this patch.
o If you encounter problems with DirectX 12, we recommend turning it off again. There are no visual or gameplay differences between the two DirectX versions.
o As always, make sure that your drivers are up to date.

Known DirectX 12 issue:
– There is a known bug that causes some very high end cards to regress relative to DirectX 11. This bug is being addressed by the development team.

While we expect this patch to be an improvement for everyone, if you do have trouble with this patch and prefer to stay on older versions, we have made a Beta available on Steam, v1.0_build524.6, v1.0_build524.7, v1.1_build524.10, v1.2_build524.15 and v1.3_build524.17 that can be used to switch back to previous versions.

We will keep monitoring for feedback and will release further patches as it seems required. We always welcome your feedback!
